Hi Christopher, the problem is not the the power consuming procceses. It is normal that processing of videos or graphis are power consuming.
I see no reason that the processor overheat if both processors are used at 100%. Before Precise it works and under Windows too. Powersave brings my processors to work at 1GHz every time. With Ondemand it switches between 1, 1.33 and 1.88GHz. If the processors go to hot the Linux should reduce the VID or automaticaly lower the CPU frequence for while. I circumvent the problem by my private pearl script which switches between powersave and ondemand. I attach the script for understanding. I would like to take a look in the source where the VID is set to understand the problem. But I don't find the rigth source module. As a summary the top power comsuming tasks are normal and need not to be identified. Hope this clearify and regards Rainer ** Attachment added: "Pearl script to bypass overheating of cpu" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1164557/+attachment/3909443/+files/temp-ctl.pl ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1164557 Title: [Lenovo ThinkPad R60] Laptop to hot - VID to high Status in “linux” package in Ubuntu: Confirmed Bug description: My laptop goes to very high temperature. First I think it was a fan problem. I adjusted thinkfan to use the disengaged option. Now my fan is at maximum speed if the temperature goes over 67°C. But still it is not possible to run the laptop for a longer time an 100% CPU. It then overheats and stops working. For example just after clamscan starts working the fan is at maximum speed (5600 revolutions) and the temperature goes up over 85°C, the CPU usage is the about 70%. My standard governer is "ondemand". By using "powersave" the temperature will be about 5-10°C decrease. My investigation show me that in my opinion the VID is to high. To verify this I do the following: - rdmsr -p0 [1] 0x0199 for every speed steps - the governer "ondemand" switches the MSR 0x199 between - 0x0613, which means 1GHz and 1.275V? - 0x081c, which means 1,33GHz and 1.3875V? - 0x0b28, which means 1,83GHz and 1.5375V? > by 100% CPU the laptop overheats and stops - set the governer to userspace 1.833GHz - reduce the VID using: wrmsr -p0 [1] 0x0199 0x0b20 > the temperature goes not over 65°C by starting load that goes to 100% CPU!. I see that the VID is always set to 0x0b28 when the governor change the speed to the highest speed. I don't know if the governor or an other kernel module set the VID The Sped (FID) is selected by the governor. The FID/VID vor maximum should be set to 0x0b20 instead 0x0B28 and every thing would fine. sudo lshw -C display; uname -a; lsb_release -a *-display description: VGA compatible controller product: Radeon Mobility X1400 vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=radeon latency=0 resources: irq:16 memory:d8000000-dfffffff ioport:2000(size=256) memory:ee000000-ee00ffff memory:ee020000-ee03ffff Linux BN591-LINUX 3.2.0-40-generic-pae #64-Ubuntu SMP Mon Mar 25 21:44:41 UTC 2013 i686 i686 i386 GNU/Linux No LSB modules are available.
